3 SAFETY 3.1 Safety statement

The RotoClone™ DownVent supplied by AAF International is a compact, self-contained dust collector. For ease of shipping and handling, the assembly ships in three parts. The body of the dust collector ships completely assembled and upright, while the top mounted fan and silencer ship separately for installation on-site. The equipment is designed to be easily handled and maneuvered using a standard forklift, hoist, or crane. The product requires two electrical connections to be made and these will need to be field wired. The equipment also includes high speed rotating components.

At all times when dealing with industrial equipment such as dust collection equipment, personnel safety must be the highest priority of all involved, from riggers, installers, operators, users, and maintenance personnel. Those responsible on-site shall review the details of the equipment beforehand and develop a plan for dealing with all stages of the installation from receipt of the equipment on-site to start-up, commissioning, and hand-over. All applicable Federal and State OSHA rules and regulations shall be fully complied with at all times. 3.2 Safe working practices and staff training

AAF International is fully committed to the safety of its employees and those of its customers. In this spirit, the following guidelines are offered for the consideration of those responsible:

• AAF strongly urges the owner to develop written safety policies, procedures, and training manuals and that all personnel be made familiar with these documents and receive safety training specific to the site, the task, and the conditions under which the work will be conducted. This shall include instruction on the hazards associated with working with potentially explosive dusts such as those resulting from the working of light metals, see paragraph 3.3 for further guidance.

• All personnel shall be equipped with appropriate personal protective

equipment (PPE) such as clothing, footwear, hard-hats, gloves, ear protection, ear protection, eye protection, and safety harness.



• All personnel involved in any stage of the process shall have been trained for the tasks in which they will be involved and at all times shall be under the direct supervision of experienced supervisors and managers.

• All personnel shall be equipped with appropriate tools and equipment to

safely and efficiently complete their task.

• Adequate lighting shall be supplied at all times while work is being conducted.

• During installation, start-up and maintenance, a work perimeter shall be set

up to define the limits of the area within which the work will be conducted and outside which there will be no threat to the safety of personnel or plant. The perimeter shall be taped-off and marked appropriately to prevent accidental ingress of uninvolved personnel or equipment. When the work area impedes into existing access ways or traffic routes for which no practical alternative is available, barriers, wardens and flaggers shall be employed to safely control crossing traffic and personnel.

• At any time only those personnel directly involved in completing the task at hand shall be allowed within the work perimeter.

3.3 Dust explosion hazard

The RotoClone DownVent is intended to be used to capture airborne particulate matter, otherwise known as dust.

Many dusts have the potential to be explosive. Dust explosions constitute a

serious industrial hazard and may result in death, serious injury, and devastating property damage. It is the responsibility of the user to identify the nature of the dust generated during any process or activity, whether or not it poses an explosive hazard, and to properly mitigate this hazard.

Except as otherwise expressly provided in writing, AAF makes no

representation or warranty in connection with explosion hazard equipment, including, but not limited to, the necessity or effectiveness of explosion hazard equipment or to the design, installation, operation, and performance of such equipment.



The basic standards for dealing with explosive dust applications are published by the National Fire Protection Agency (“NFPA”). The user shall be fully conversant with the provisions of the particular codes and standards that apply to the specific application and equipment used, and shall comply in full with all of the requirements of the applicable codes and standards.

3.3.1 NFPA 654 and referenced codes and standards

The owner shall review and comply with NFPA 654: Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, and those other documents referenced therein. NFPA 654 pertains to “all phases of manufacturing, processing, blending, conveying, repackaging, and handling of combustible particulate solids or hybrid mixtures, regardless of concentration or particle size, where the materials present a fire or explosion hazard”. The purpose of the standard “is to prescribe technical requirements for safety to life and property from fire and explosion and to minimize the resulting damage from a fire or explosion”. The user shall be fully conversant with the provisions of NFPA 654 and shall comply in full with all of its requirements and those of all applicable referenced codes and standards.

3.3.2 NFPA 484, Light Metals

There are various methods for dealing with a dust explosion hazard. The RotoClone DownVent is particularly appropriate for the collection of dust generated by the working of light metals such as aluminum, titanium and magnesium. These dusts are highly explosive and the RotoClone DownVent uses water as a medium for neutralizing the development of a potentially explosive dust cloud and for eliminating the possibility of ignition. The specific standard that applies to these applications is NFPA 484: Standard for Combustible Metals. This standard applies to “the production, processing, finishing, handling, recycling, storage, and use of all metals and alloys that are in the form that is capable of combustion or explosion 1 ”. When the RotoClone DownVent is used to collect dust from the working of light metals the user shall be fully conversant with the provisions of NFPA 484 and shall comply in full with all of its requirements. 3.3.3 Other requirements

The use of a dust collector for the collection of explosive dust is only one part of a safe dust prevention and mitigation program. Dust shall not be allowed to

1 Ref: NFPA 484: Standard for Combustible Metals, 2015 Edition, Paragraph 1.1, Page 484-8



accumulate or build up on the surfaces of the dust collector, on the air intakes or in the surrounding area. The owner’s attention is directed particularly to the “Housekeeping” chapters in NFPA 654 (Chapter 8 in the 2013 edition) or NFPA 484 (Chapter 7 in the 2015 edition). If any of the other codes and standards referenced above apply, consult the appropriate chapters in those documents.

The editions referenced here were current at the time of writing. Be aware that they may have changed. When referring to NFPA standards the user shall ensure that they are working with the most current edition. For information on NFPA® standards, go to http://www.nfpa.org/ .

3.4 Electrical hazard

Before doing any work on the AAF equipment, make sure that all potential electrical hazards have been identified and that all electric current connected to the equipment, and to any connected or associated equipment, has been properly

disconnected and securely locked-out to prevent accidental reconnection prior to completion of the work.

Electrical power is connected to the

RotoClone DownVent control panel, which is installed on the sidewall of the dust collector cabinet, and from there to the fan motor, the solenoid valve, and the workspace light. All power MUST be connected through the control panel. Under no circumstances shall the control panel ever be by-passed. The control panel door shall not be opened until all electrical power has been disconnected from the dust collector and locked out. The only exception to this is when diagnostics are being performed by a licensed electrician.

Before performing any electrical work the wiring diagram shall be reviewed.

http://www.nfpa.org/



All electrical work shall be done in full accordance with the current edition of

NFPA 70, the National Electrical Code, and all appropriate governing local codes. All electrical work shall be performed by a licensed/qualified electrician. Only original AAF parts shall be used as replacements for ongoing maintenance and repair. 3.5 Rotating equipment

The RotoClone DownVent includes a fan which is installed on the top of the dust collector. The fan wheel can rotate at a nominal speed of 3,600 rpm and has the potential to cause severe injury. The fan wheel could be accessed from inside the cabinet through the air inlet if the moisture eliminator is removed, and from outside the cabinet through the fan discharge. All due care should be exercised to avoid any contact with the operating fan. Under no circumstances should the fan ever be allowed to operate when any of the access panels on the dust collector, or the silencer, have been removed. The

fan must be disconnected and locked out prior to the performance of any maintenance work, see paragraph 3.4.



3.6 Safety guards The dust collector cabinet prevents access to the fan inlet. All access panels

shall remain bolted in place while the fan is operating. Prior to the removal of any access panel, the electrical power to the collector shall be disconnected and locked out, see paragraphs 3.4 and 3.5. After electrical power is disconnected, the fan wheel will continue to rotate for a period of time before coasting to a stop. Do not access the fan until the fan wheel has come to a complete stop.

A safety screen is supplied on the 90 degree

outlet silencer that ships separate for connection to the fan discharge. This screen is bolted to the outlet flange. Under no circumstances should this screen be removed while the fan is in operation or when there is electrical power connected to the dust collector.

4 GENERAL PRODUCT INFORMATION 4.1 Description

The RotoClone DownVent is a mostly factory assembled, fully self-contained unitary dust collector. Note that the top-mounted fan and the 90 degree outlet silencer ship separately for installation at the site. The DownVent includes a DownVent bench-style working surface that is typically used for cutting, grinding, buffing and polishing small parts. The dust generated by these operations is drawn by the DownVent airflow through the grid that forms the working surface, first into a water bath and then through AAF’s unique static impeller which causes the dust to mix thoroughly with the water and separate from the air. The cleaned air is then emitted from the dust collector through the fan located on top of the collector and separated dust settles to the bottom of the water bath. The dust forms a sludge which is then periodically removed from the collector.

All of the wetted parts of the RotoClone DownVent, including the impeller, are manufactured from type 304 stainless steel. The superstructure is carbon steel. All exterior metal surfaces and carbon steel interior surfaces are painted. The working surface grid is fiberglass reinforced polyester (FRP).

The DownVent is fitted with a light to illuminate the work surface.



The NEMA 12 control panel is mounted on the side of the dust collector and pushbuttons and a switch control the operation of the fan motor and the light.

The RotoClone DownVent can only be operated when it is filled with water to the correct level. Automatic cut-out devices prevent operation of the fan if the water level is too low. 4.2 Purpose and intended use

The RotoClone DownVent is a combination bench style work-station and dust collector. It is intended for the collection of dust generated by the working (e.g. cutting, grinding, buffing or polishing) of metals and non-metallic materials. 4.2.1 Collection of explosive dusts

The RotoClone DownVent is primarily intended for the collection of dust generated by the working of light metals such as aluminum, titanium, and magnesium. Such dusts have the potential to be highly explosive if not dealt with correctly. See paragraph 3.3 “Dust explosion hazard” for further details.

The RotoClone DownVent neutralizes the threat of a dust explosion by encapsulating the captured dust in water and preventing the development of both a dust cloud that might reach the explosive limit and of any potential ignition source.

It bears repeating here that the use of a dust collector for the collection of explosive dust is only one part of a safe dust prevention and mitigation program. Dust shall not be allowed to accumulate or build up on the surfaces of the dust collector, on the air intakes or in the surrounding area. The owner’s attention is directed particularly to the “Housekeeping” chapter in NFPA 484 (Chapter 7 in the 2015 edition). 4.2.2 Collection of other dusts

In addition, the RotoClone DownVent can also be used to collect dust generated by the working of other metallic and non-metallic materials that may not present an explosion hazard. 4.3 Normal Operation

During normal operation, the user stands in front of the RotoClone DownVent and performs work on parts supported on the grid-style bench top work surface. The control panel located on the side of the RotoClone DownVent has an ON/OFF



switch to control the light mounted above the work surface and START and STOP pushbuttons to energize the fan.

CAUTION: The fan must be operating whenever dust is being generated. If it is not, stop work immediately

Air is drawn downwards through the grid that forms the work surface and carries the dust generated by the operation with it. The RotoClone DownVent has a unique stationary impeller which creates a violent mixing action that transfers the dust particles from the air to the water. The wetted dust then settles to the bottom of the collector from where it can be removed automatically or manually. The cleaned air is exhausted from the collector after passing through a permanent bank of moisture elimination baffles which removes any remaining moisture droplets from the air.

A permanent supply of water must be provided to the RotoClone DownVent at all times to ensure that any water lost from evaporation or from removal of the collected sludge is immediately replaced. It is critical that the water level be at the correct level to ensure that the stationary impeller functions properly. The RotoClone DownVent controls will shut down the fan if the water level is allowed to fall too low.

CAUTION: A proper water level must be maintained whenever dust is being generated. 4.4 Sizes and Physical Characteristics

The RotoClone DownVent also has lifting lugs mounted on the top. Each size of RotoClone DownVent is fitted with four lifting lugs, one at each corner. These may be used to hoist the product instead of lifting it using the shipping pallet. All lifting lugs must be used when hoisting the product. When using the top mounted lifting lugs, use spreader bars at all times. Position the spreader bars so that the force applied to each lifting lug is vertical and not angled. Also make sure that lifting straps or cables do not come into contact with any other part of the product to prevent the possibility of damage from abrasion. Before hoisting, make sure that the load is properly balanced. At the beginning of the lift, hoist the product slowly and carefully. 7.4 On-site transportation

Before transporting the product on-site, review 7.2 “Handling” and 7.3 “Rigging and hoisting instructions”. The RotoClone DownVent may be transported by forklift, in which case it must remain on its original shipping pallet, by travelling hoist, or using an overhead crane.

After placement of the body of the RotoClone DownVent, the fan and

silencer will have to be hoisted to the top of the RotoClone DownVent for installation.



8 STORAGE AND PROTECTION If not installed immediately, the equipment shall be retained and stored in a

protective environment until immediately prior to installation. This environment shall be clean, dry, and temperature and humidity-controlled.

At all times, the equipment shall be protected from exposure to weather and

from standing water. All equipment shall be stored on its original shipping pallet so that it is

elevated above grade. The equipment shall be clearly labelled and be stored in a location that is

easily and readily accessible. If prolonged storage is anticipated, the equipment shall be covered with

plastic to prevent the accumulation of surface dust. In the case of prolonged storage, a maintenance schedule shall be set up to periodically rotate fan wheels to prevent bearing degradation.

9 SITE PREPARATION 9.1 Locating equipment

The equipment shall be located in an area with sufficient space to allow ready access. It is recommended that at least 4 feet of clear space be available at each side of the equipment and 3 feet to the rear for access and maintenance. At the front of the product is a down-flow workbench. The user will stand in front of the bench to perform work. For this reason, it is critical that the RotoClone DownVent be set well back from traffic lanes within the plant, that there be adequate space for the worker to maneuver, and if necessary that there also be adequate space for unfinished and finished parts bins. The customer shall determine if it is necessary to erect permanent guards or railings for the protection of the worker.

Ensure that the installation location of the RotoClone DownVent is suitable

for the noise levels generated during operation and use. The RotoClone DownVent requires a 3-phase power supply, a continuous

main quality water supply, and access to a drain. If these services do not exist at the desired location, they should be installed prior to installation of the equipment.



The power supply required is defined for each size of RotoClone™ DownVent in table 9.1 below. CAUTION: Consult the purchase order for the size and voltage ordered.

9.2 Preparation of supports

The RotoClone DownVent mounts directly on its base at grade level. It shall be supported on a flat, smooth, horizontal, reinforced concrete base pad which allows the worker/user to stand at the same level as the base of the equipment. Provisions for anchor bolts shall be provided in the concrete base pad. 9.3 Foundations

The support foundation must be designed to be adequate to support the RotoClone DownVent operating weight, and any seismic, live or other loads (if any), with a sufficient factor of safety as determined to comply with the requirements of all applicable governing codes, standards, and laws. Ensure that the foundation or support surface is flat, level, and smooth before proceeding. The RotoClone DownVent is designed for indoor operation only.

The reinforced concrete base pad shall provide adequate embedment for the anchor bolts.



9.4 Anchoring Each RotoClone DownVent includes a base flange on the left and right hand sides and each flange contains 2 holes to accommodate anchor bolts, for a total of 4 anchor bolts. All anchor locations must be used. The anchor bolt holes are 7/8 inch in diameter. The anchor bolts shall be supplied by the customer. Anchor location (4 supplied)

9.5 Support structure

The RotoClone DownVent is self-supporting, mounts directly on its base at grade level, and does not require a support structure other than the foundation and anchor bolts referenced in 9.2, 9.3 and 9.4.

10 ASSEMBLY AND INSTALLATION 10.1 Introduction

Before beginning installation, the installer shall note the following:

• For the RotoClone DownVent to operate properly and safely, it must be installed correctly in full accordance with these instructions. Improper installation will void the product warranty.

• Permits, approvals or licenses may be required prior to installation and operation of the equipment. The owner shall consult with the relevant local, state, and federal government authorities to obtain information on the regulations that apply and the approvals and documentation that must be obtained.

• Installation of the RotoClone DownVent shall be supervised by

personnel experienced in the installation of dust collection equipment. The completed installation shall be inspected and approved in writing by a qualified inspector.

• Ensure that all shipping covers and other materials that are not part of the RotoClone DownVent have been removed from the equipment



before installation begins. Failure to remove such items could cause the equipment to be unsafe or to perform inadequately.

• Examine the RotoClone DownVent carefully and ensure that there are no loose or missing parts, and that all hardware is installed tightly. Once the site of the RotoClone DownVent installation has been prepared in

accordance with section 9, the equipment can be installed. After reviewing this manual, the customer shall determine the number and the trade-skills of the personnel required to complete the installation. The following are recommended:

• A fork-lift and hoist or crane operator/rigger • Two installation mechanics • A plumber • An electrician

10.2 Tools

No special tools are required to install the product. The tools required are the typical tools found in any mechanic, electrician, or plumber’s toolbox. It is also recommended that two 12-foot tall minimum step ladders be available for use during installation. 10.3 Machinery for handling, lifting and assembly

See section 7 “Unloading and handling”. The same equipment referenced in this section will be used in the installation of the RotoClone DownVent.

10.4.2 The main body of the RotoClone DownVent

Using the four (4) lifting lugs located on the top of the assembly, lift the RotoClone DownVent off its shipping pallet into position on its foundation pad and place the base mounting holes over the anchor bolt locations.

The RotoClone DownVent is a wet dust

collector that uses water as the filtering medium. In order for it to operate properly, it is critical that the equipment be absolutely level. After placement, check the base of the equipment to make sure that it is level in both directions, along both sides and along the front and back. If necessary, adjust the base using shims until it is level.

Secure the anchor bolts to rigidly connect

the equipment to its foundation pad. Grout any gaps between the base flanges and the support foundation after leveling so that the equipment

is uniformly supported. 10.4.3 Fan

See 10.4.4 for instructions on how to connect the silencer to the fan outlet. The installer may decide to connect the silencer to the fan before raising the

fan to the top of the collector. Be aware that this may cause the fan to be unbalanced when being hoisted and care should be taken during this operation.

Install a ¼ inch diameter bead of caulk onto the circular outlet flange of the

RotoClone DownVent making sure to provide a circle of caulk around each bolt hole.



Lift the fan off its shipping pallet using the four (4) lifting lugs located on the top of the fan scroll and hold it in position above the circular outlet flange.

Rotate the fan until the

fan discharge is located in the desired position.

Depending on the fan

position selected, it may be necessary on the Size 2 RotoClone DownVent to remove one of the lifting lugs to accommodate the fan outlet.

When the lifting lug has been removed, replace the hardware in the bolt holes and seal beneath the washers with caulk.

CAUTION The lifting lugs on the fan shall ONLY be used to hoist the fan, they shall NEVER be used to hoist the fan and filter housing assembly together.

The fan motor is fitted with a lifting eye. This lifting eye shall only be used to lift or support the motor. It shall NEVER be used to support the full weight of the fan.



Lower the fan vertically onto the outlet flange using bolts or drift-pins to match the holes in the fan flange with the holes in the outlet flange. Continue to support the fan with the hoist until it has been securely connected to the RotoClone DownVent. Once the fan has been positioned, bolt the fan flange to the outlet flange with the hardware supplied. Torque the bolts to the required value.

10.4.4 Silencer

Install a ¼ inch diameter bead of caulk onto the rectangular outlet flange of the RotoClone DownVent fan, making sure to provide a circle of caulk around each bolt hole. It is suggested that straps be secured beneath the outlet flange of the silencer to raise it into position. Lift the silencer off the shipping pallet and match the inlet flange of the silencer to the outlet flange of the fan. Connect the silencer to the fan using the hardware supplied. Torque the bolts to the required value.



10.4.5 Electrical connections

Two electrical connections will be required to be made.

The electrical wiring and flexible wiring conduit that serves the fan motor ships installed on the control panel. Connect this to the motor conduit box using the connector supplied.

See the motor nameplate for the wiring connections to the motor.

Connect the appropriate power

wiring to the control panel. Refer to the wiring diagram. This will require the installer to

drill an access hole in the control box and provide the appropriate connection fittings.



10.4.6 Water supply connections

There are two water supply connections that must be made.

First, connect the supply line to the ¼ inch

diameter FPT thread on the solenoid valve. The valve will be normally closed when the power is off.

Second, connect the supply line to the 1

inch diameter FPT thread on the manually operated water supply valve. Make sure that the valve is in the closed position until the equipment is ready to be made operational.

10.4.7 Drain connections

There are two water drain connections that must be made.

First, remove the plug in the overflow connection and connect a drain line to the 1 inch diameter FPT thread

Second, connect the drain line to the 2 inch diameter FPT thread on the manually operated drain valve. Make sure that the valve is in its normally closed position with the handle parallel to the side of the RotoClone™ DownVent.

IMPORTANT: Provide a clean-out Y-fitting at the connection to the valve for cleaning and back-flushing in case the drain should become clogged.



10.4.8 Filling the RotoClone™ DownVent with water A

Before starting the RotoClone DownVent fill it with water to a “Minimum Water Fill Line Fan Off” level approximately 2 inches below the level of the bottom of the water level probe, shown here as the “Operating Water Level Fan On” line. Note that the markings referenced are shown here for illustration only and do not actually appear on the equipment.

During operation, the negative pressure induced by the fan on the clean-air (downstream) side of the RotoClone DownVent will pull the water level up to the probe. Water must be touching the probe for the fan to continue to operate. The water may actually rise above the bottom of the probe at start-up. This is acceptable. It will eventually adjust itself to the proper level. See section 11 “Start-up and Operation” for further discussion of this.

When the fan is turned off, the pressure differential is removed and the water level drops to the “Fan-Off” level. Approximately 2 inches

Open the manually operated water supply valve and allow the RotoClone DownVent to fill to the “Minimum Fan-Off” level (approx.. 2 inches below the bottom of the probe). This is a “minimum” water level and it is acceptable for the water level to rise slightly above this line. The maximum “Fan-Off” water level is defined by the bottom of the overflow drain connection. When the water level reaches or slightly exceeds the “Fan-Off” water level line, close the water supply valve.



10.4.9 Side Panels

The RotoClone DownVent is equipped with hinged side panels that are both moveable and removable.

The purpose of the side

panels is to enclose the work surface and channel the airflow that captures the dust that is being generated. They also serve as impact surfaces that prevent dust generated by rotating equipment from being propelled from the sides of the work surface.

At this time, based on the intended use of the RotoClone DownVent, the end user may decide to remove some or all of these panels.



To remove the panel, first disengage the spring clip which holds the panel in position.

Next, lift the panel so that the barrel of the hinge which is attached to the panel is raised off the pin, which is attached to the RotoClone DownVent.

Store the panels for future use or discard if not needed.



11 START-UP & OPERATION 11.1 Start-up checklist

Before starting up and operating the equipment, thoroughly inspect the installation to ensure that it is complete and that the RotoClone DownVent has been installed in accordance with this manual. Before start-up and operation, all personnel who will operate or maintain the equipment shall be trained in its use. This checklist provides the minimum requirements. In-plant or purchaser quality and inspection procedures may exceed this list. CAUTION: For the safety of all personnel and to ensure proper and safe use and operation of the RotoClone DownVent, confirm and check-off each item listed before starting-up and operating the equipment

20 The 1” inch diameter manually operated water supply valve is in the closed position.

21 The work surface is properly installed at the front of the RotoClone™ DownVent



11.2 Starting the RotoClone™ DownVent Starting the RotoClone DownVent could not be simpler. The control panel

features one switch and two push-buttons:

The switch turns the front mounted light on and off. The pushbuttons start and stop the fan

Turn on the light and push the start button and the RotoClone DownVent is

ready for use.



11.3 Normal operation

During normal operation the user stands in front of the RotoClone DownVent and performs work on a part that rests on the horizontal grid. It is assumed that the work performed produces dust. The open grid work surface allows air to be pulled into the dust collector.

When the fan is energized,

air is drawn around the user, captures the suspended dust that is being generated and pulls it down through the grid into the

water bath.

As the contaminated air enters the water bath, the mixing between the contaminated air and the water begins.



The air / water mixture then enters the stationary impeller where, through a combination of induced aerodynamic and hydrostatic forces, the majority of mixing and wetting takes place resulting in the transference of the dust to the water.

The dust encapsulated in the water then settles to the bottom of the collector where it forms a layer of sludge.

The cleaned air

passes out of the impeller and into the moisture eliminator, where any encapsulated water droplets are removed. The water captured by the moisture eliminator returns by gravity to the water bath. Finally, the cleaned air enters the fan, passes through the silencer, and is exhausted to the ambient environment.



11.4 Control system

Some loss of water can be expected through evaporation and from the removal of collected product. However, it is critical to the operation of the RotoClone DownVent that the water level be maintained at the required level. This is accomplished by the RotoClone DownVent control system.

The water level is monitored by a sensing system which uses a contact

probe located in a transparent tube on the outside wall of the equipment to ensure that the water level is correct. If, after the fan is energized, the water level does not rise to contact the probe within 2 minutes, the solenoid valve is opened to supply additional water. Simultaneously, the on-delay timer is activated. If, before 3 minutes has elapsed, the water contacts the sensor, the on-delay timer will be de-activated and the equipment will continue to operate normally. If, after 3 minutes, the water has not contacted the sensor the fan will shut down and corrective maintenance will be required.

See the following detail of the control panel and the wiring diagram for further details:

11.5 Wiring diagram



11.6 Removal of collected material Periodically, the collected sludge must be removed from the RotoClone

DownVent. It is recommended that this be done whenever the depth of the sludge has reached a maximum of 2 inches for light metals or 6 inches for other dusts. The frequency of this requirement depends entirely on the quantity of dust generated by the duty cycle and nature of the work being performed on the work surface of the RotoClone DownVent.

WARNING: When disposing of the collected material and contaminated water it is the responsibility of the user to determine the constituents of the material and to comply with all relevant local, state, and federal government standards, codes, laws, and policies regarding the handling and disposal of such materials and the safety of all who may come in contact with them.

It is recommended that the sludge be removed if the equipment is expected

to be out-of-service for any prolonged period of time. The sludge depth shall be checked periodically during the first week (or weeks) of operation and an “average rate of accumulation” determined. Based on this a schedule shall be established for how often the sludge must be checked and removed.

The sludge may be accessed by removing the grid that forms the RotoClone DownVent work surface and probing the depth of the collected material. If possible, the RotoClone DownVent should be shut down for a few hours prior to cleaning to allow the entrapped solids to settle.



The collected sludge may be removed when the RotoClone DownVent is “wet” or “dry” and may be accomplished using various methods. The preferred method will depend on state of the equipment (wet or dry) and the nature of the material being collected and is best determined based on trial. For instructions on draining the RotoClone DownVent see 11.7 below. The simplest method of removing the sludge is to remove the work-surface grid and rake the sludge up the sloping front face of the RotoClone DownVent reservoir using a 12" wide hoe. Alternatively, mud or sludge pumps are available from several suppliers. These can be used to pump the settled material into a suitable disposal container. 11.7 Draining the RotoClone™ DownVent

To drain the RotoClone DownVent, open the manually operated drain valve at the base of the equipment. To reduce the risk of clogging the drain open the valve slowly so that the water flow increases gradually.

Initially, the outflow of water

will cause a small amount of the sludge layer to erode away in the vicinity of the drain inlet. After this

“channeling” has taken place the water should flow clear and leave the remainder of the sludge layer intact in the base of the RotoClone DownVent.

If the drain becomes plugged, probe the drain with a rod or backflush it with

a pressure hose through the user supplied clean-out installed with the drain piping. Sludge can also be pulled away manually from the inside the RotoClone DownVent at the drain inlet to re-establish the flow.

Plugging of the drain is an indication that the frequency of cleaning should

be increased.



12 MAINTENANCE To ensure proper operation of the RotoClone DownVent, these procedures should be followed as a minimum. More frequent cleaning may be required for certain applications. 12.1 Water level

Check the water level in the RotoClone DownVent frequently. Make sure that the water level is at the correct levels. See 10.4.8 for further information. 12.2 Inspection and cleaning

Drain the RotoClone DownVent once per month initially and inspect the items listed below. After draining, remove the grid that forms the work surface and the rear access door which is bolted on. If no build-up of material is observed, and the equipment usage does not change, the interval between inspections can be increased. Conversely, if excessive build-up is observed, the interval shall be decreased.

• Remove all collected sludge from inside the base of the housing.

• Inspect all housing surfaces for accumulation of material.

• Inspect the impeller surfaces for accumulation of material. The front of the impeller can be accessed from the front of the equipment through the work surface opening and the rear of the impeller can be accessed through the rear access door opening.

• Inspect the moisture eliminator for accumulation of material. The moisture eliminator can be accessed through the rear access door opening.

Typically any accumulations of material can be removed by washing down with a high pressure hose. 12.3 Fan and motor

At each maintenance check, inspect the fan and motor for excessive vibration. If there is excessive vibration, review the fan and motor troubleshooting guide below. AAF International uses a number of reputable fan and motor suppliers, each of which will have specific recommendations for the maintenance of the products



supplied. Maintenance instruction sheets are typically included in the motor conduit box. Save those instructions along with this manual for future reference. If the referenced instructions are not available, note the information on the motor nameplate and access the manufacturer’s web site or contact the manufacturer directly for information on maintenance.

The following instructions are supplied for general guidance only and the manufacturer’s instructions will take precedence. 12.4 Fan and motor lubrication

Typically these are ball bearing motors. The bearings will have been lubricated at the factory. Motors that do not have re-grease capability are factory lubricated for the normal life of the bearings. 12.5 Re-lubrication intervals

This only applies to motors with re-grease capability. New motors that have been stored for a year or more should be re-lubricated. Lubrication is also recommended at these intervals:

Typical Re-lubrication Intervals NEMA (IEC) Frame Size Rated Speed (RPM)

3600

Up to 210 incl. (132) 5500Hrs. Over 210 to 280 incl. (180) 3600Hrs.

12.5.1 Lubricant

Check with the motor manufacturer for recommendations.

Typically, for best results, the grease used should be a good grade of petroleum oil of No. 2 consistency and stabilized against oxidation. Operating temperature range should be from -15"F to +250'F for Class B insulation, and to +300'F for Class "F" and "H". Most leading oil companies have special bearing greases that are satisfactory.



12.6 Lubrication procedure Clean the grease fitting (or area around grease hole, if equipped with slotted

grease screws). If the motor has a purge plug, remove it. Motors can be re-greased while stopped or running.

Apply the grease gun to the fitting (or grease hole). Be careful not to over-grease. The addition of too much grease or the injection of grease too quickly may result in premature bearing failure. Slowly apply the recommended amount of grease, taking 1 minute or so to apply. Operate the motor for 20 minutes, then reinstall the purge plug if previously removed. CAUTION: Ensure that the grease is new and clean. Mixing of different greases is not recommended.
